App doesn't update

[Anke]

To what extent is this an explanation and solution to the (alleged) problem?

When I click on the green button I go to a 404 html page

No problem from my side.
Can you give a screenshot of the error, with the url on it.

I do not know how to explain any better sorry.
I have managed to duplicate my mistake and thereby make my app update THANKS COMPLETELY TO YOUR help in post 53

I cannot thank you enough

Also a BIG thank you to @ChrisWard

To finally conclude and clarify:
If I subsequently change the project name of my AIA from post 53 (appName.aia) to "appName_2.aia", this of course does not change the packageName (as shown in the following image):

Only when I import the AIA renamed "appName_2.aia" into AI2 and then export or compile it again do I get "appinventor.ai_bodymindpower.appName_2" as the packageName.

This is my final statement, not least to avoid confusion for other users.
